2.6
Connection of the sauna heater to the mains
The sauna heater must be connected to the mains by a qualified electrician and in compliance with current
regulations. The sauna heater is connected with a semi-permanent connection. Use H07RN-F (60245 IEC 66)
cables or a corresponding type. Other output cables (signal lamp, electric heating toggle) must also adhere to
these recommendations. Do not use PVC insulated cable as a connection cable for the sauna heater.
A multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control current
fuse, the diameter of all cables must be the same, i.e. in accordance with the front fuse.
The connecting box on the sauna wall should be located within the minimum safety clearance specified for the
sauna heater. The maximum height for the connection box is 500 mm from the floor. See page 9. Figure 3
Locating the connecting box for the connection cable in the sauna room
If the connection box is located at over 500mm distance from the heater, the maximum height is 1000mm from
the floor..

NOTE:
Controlling the lights in the sauna with the circuit board is only possible with resistive loads (incandescent
light bulbs). The circuit board relay cannot withstand capacitive loads (switched-mode power supply units). If the
lighting fixtures in the sauna have transformers, for example LED or halogen lamps, the stove circuit board's relay
control must be fitted with a separate relay or contactor for controlling the lights.
Sauna heater insulation resistance:
The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause leakage
currents. The moisture will be gone after a few heating sessions. Do not connect the heater power supply through
a ground fault interrupter.
However, adhere to the effective electrical safety regulation when installing the sauna heater.
2.7 Electric heating toggle
Electric heating toggle applies to homes with an electric heating system.
Sauna heater has connections (marked N-55) for controlling the electric heating toggle. Connectors N-55 and the
heating elements are simultaneously live (230V). The sauna heater thermostat also controls the heating toggle. In
other words, home heating turns on once the sauna thermostat cuts power off the sauna heater.

Installation and User Manual
HELO Roxx premium
Remove the nut and the rubber grom-
met from the strain relief bushing. Make
a vertical split in the spot where the
lead-in rubber grommet aligns with the
hole. Insert the control panel's and
sensor OLET 31 cable through the
strain relief bushing and insert the cable
through the splitted holes. Tighten the
strain relief bushing nipple.
